Microtextures of Cyanobacterial Mats in Siliciclastic Sedimentary Environments (Modern & Ancient): Applications to the Search for Life on Mars
… Bay. To describe and to quantify various microtextures such as bacterial filaments, extracellular polymeric substances, mat fabrics, etc., I coupled morphometric and geochemical analyses. Optical microscopy and confocal scanning laser microscopy (CSLM) revealed that the morphology and …

Precision rotational rheometry
… of the gap in order to explore the effect of microtextures on shear stress. We have also correctly non-dimensionalized the system and validated it with numerical results. Results show that the reduction in shear stress is larger than numerical results predict.

Droplet levitation and underwater plastron restoration using aerophilic surface textures
… utility of this method by fabricating periodic microtextures on aluminum surfaces that incorporate a cheap catalyst, manganese dioxide. We perform drag reduction experiments under turbulent flow conditions in a Taylor-Couette cell which show that more than half of the drag increase ensuing from …

How beetles explode : new insights into the operation, structure, and materials of bombardier beetle (Brachinini) defensive glands
… highly complex, with a number of distinct spiny microtextures localized to specific regions of the reaction chamber. Quantitative details of the spine lengths and spacings are reported, and on the basis of the similarity of some of the features to the beetles' external abdominal microscupture and …

Phosphorus Pathways In Deep Time
… of P mineral distribution and associated microtextures in each lithology is presented. I observe continuously strained as well as recrystallized strain-free merrillite populations. Grains with strain-free subdomains are present only in the more intensely shocked dark lithology, indicating …

Ανασύνθεση παλαιοπεριβάλλοντος σε παράκτιες γεωμορφές της νότιας Κύπρου με την χρήση τεχνικών φωταύγειας
… developed into a method for linking sand-grains microtextures to particular sedimentary environments (Krinsley and Marshall, 1987; Legigan et al. 1989). Different types of microtextures on the quartz grain surfaces can be used to differentiate between aeolian, marine, and glacial depositional …

Exploring plastron stability and fluid friction reduction on robust micro-textured non-wetting surfaces
… trapped air (or 'plastron') within the surface microtextures upon contact with a liquid. A combination of texture and surface chemistry is also important in the design of various biomimetic interfaces. Many species of aquatic birds dive tens of meters into water to prey on fish while entraining …
